When it comes to tarp hire, securing the tarp correctly is just as important as choosing the right one.
A poorly secured tarp can lift in the wind, allow water to enter, or even create safety risks on-site. For builders and owner-builders, getting this right is critical especially during storms, renovations, or insurance make-safe work.
This guide focuses on how roof tarps are actually secured on-site in Australia using ropes, eyelets, underties, and weights.
Why Proper Tarp Securing Matters
Roof tarps are often installed in urgent situations – after storm damage or when a roof is left exposed during construction.
If the tarp isn’t secured properly, it can:
• Flap or lift in strong winds
• Allow water to track underneath
• Tear at stress points
• Fail when you need it most
A few extra minutes securing it properly can prevent major damage later.
How Construction Tarps Are Designed to Be Secured
Heavy duty construction tarps are built with fixing points to make securing them faster and more reliable. At Tarp Hire Australia, our tarps include:
• Metal eyelets (grommets) for strong fixing points
• Ropes every metre along the edges
• Underties for additional securing options
This setup allows builders to tie down tarps quickly and adjust tension as needed.
Step 1: Position the Tarp Correctly First
Before securing anything, make sure the tarp is laid out properly. It should:
• Fully cover the damaged or exposed area
• Extend beyond the section being protected
• Follow the fall of the roof so water runs off
If the tarp isn’t positioned correctly, even the best securing method won’t work effectively.
Step 2: Use Ropes and Eyelets to Tie It Down
The primary way to secure a roof tarp is using the ropes and eyelets along the edges.
How this works on-site
• Tie ropes from the tarp to stable anchor points
• Work your way around the perimeter
• Keep tension even across all sides
This helps hold the tarp firmly in place and reduces movement in wind.
Eyelets provide strong, reinforced points so the tarp doesn’t tear under load.
Step 3: Use Underties for Extra Security
Underties give you additional fixing options, especially in areas where extra hold is needed. They are useful for:
• Securing sections that may lift in wind
• Adding tension across larger tarps
• Reinforcing high-risk areas
Using underties alongside ropes helps distribute the load more evenly across the tarp.
Step 4: Add Sandbags or Weights
In addition to tying the tarp down, weights are often used to keep edges secure. Sandbags are commonly placed:
• Along the lower edges
• On sections exposed to wind
• At key points where lifting could occur
This adds stability and helps prevent the tarp from shifting or lifting during bad weather.
Step 5: Check Tension and Adjust
Once everything is secured, do a final check. Make sure:
• The tarp is pulled tight with no loose areas
• There are no gaps where water can enter
• Edges are properly tied and weighted
If the tarp is loose, it will flap in the wind and wear out faster.
Common Mistakes to Avoid
Even on busy sites, avoiding these mistakes makes a big difference:
• Leaving slack in the tarp
• Not using enough anchor points
• Relying only on weights without tying down
• Poor positioning before securing
These are the main reasons tarps fail during storms.
Final Thoughts
Securing a roof tarp properly isn’t complicated, but it does need to be done right. Using the combination of:
• Eyelets
• Ropes every metre
• Underties
• Sandbags
…gives you a reliable setup that can handle wind and rain while protecting the structure underneath.
For builders, this is all about reducing risk and keeping the job moving.
